"Wife" sounds exactly the same in both places. All they did was copy the exact waveform from one point to another. Nothing is being synthesized.

The word "Jordan" is not being synthesized. The speaker was recorded saying "Jordan" beforehand for this insertion demo and they're trying to play it off as though it was synthesized on the fly. This is a scripted performance and Jordan is feigning surprise.

The phrase "three times" here was prerecorded.
This was a phony demonstration of a nonexistent product. Reporters parroted the claims and none questioned what they witnessed. Adobe falsely took credit and received endless free publicity for a breakthrough they had no hand in by staging this fake demo right on the heels of the genuine interest generated by Google WaveNet. I suppose they're hoping they'll have a real product ready by whatever deadline they've set for themselves.
To be clear, I like Adobe and I think it's a cunning move on their part.
